Trailmaster

I have a Trailmaster Airride pin box. I like it except it won’t hold air. I’ve changed out the valve and tested it for leaks and that’s not the problem. I’d be willing to try some green slime to stop what must be a pinhole leak. It’s on a 2016 so going on 7 yo. Otherwise i’ll replace the two airbags. Has anyone done this and if so how hard is it. I’ve priced them on Amazon and other places and they aren’t cheap. Where to get them and instruction on replacing them would be greatly appreciated. There’s probably something on YouTube

Has anyone inflated this air bag using Nitrogen? Pros or cons in using nitrogen? Maybe it will help in very slow leaks? I contribute the air pressure loss in my hitch to temperature change as sometimes after 2 weeks there is a bit of pressure loss and sometimes there isn"t.

I run nitrogen in everything now. Larger molecules then air. At first I thought it was a scam but it turns out to be true. My trailer air pressure is constant. Hasn't changed in a year.

Have you tried spraying it with soapy water to see where the leak coud be.
